Definitions

  • the invention relates to a system for introducing fuel into the exhaust gas system of a motor vehicle.
  • Modern engines burn increasingly leaner fuel mixtures, so that relatively high oxygen concentrations and nitrogen oxide concentrations result in the exhaust gas.
  • Such exhaust gases can be cleaned with modern vehicle catalysts, for example NOx storage catalysts, with a reducing atmosphere having to be generated at regular intervals to reduce the nitrogen oxides. This is most easily achieved by introducing some fuel into the exhaust line when needed.
  • the object of the invention is to show a way in which the costs of exhaust gas purification in motor vehicles can be reduced. This object is achieved by a system having the features specified in claim 1 and a fuel evaporator for such a system according to claim 3. Advantageous developments of the invention are the subject of the dependent claims.
  • An inventive system has a fuel evaporator having a housing with an inlet and an outlet and a heater disposed in the housing, and a pump to pump fuel through the inlet to the fuel evaporator to the pump.
  • the fuel evaporator can be regenerated by supplying air.
  • the supply of fresh air is advantageously achieved by means of the pump, which is present in any case for pumping fuel, so that the additional expense of a system according to the invention is minimal.
  • the same pump can be used both for pumping liquid fuel and for pumping air without being destroyed by dry-running.
  • the pump is always used only for a short time, typically 0.5 to 2 minutes, for pumping air, and then again flows through fuel, ie re-lubricated.
  • the two branches of a system according to the invention can each be shut off with a separate valve, wherein the valves are switched by a central control unit as needed in order to introduce either air or fuel into the fuel evaporator.
  • the branch is preferably a directional control valve, in particular a 2/1 way valve, with which either the first branch or the second branch can be shut off. In this way, with particularly low likes effort a system according to the invention can be realized.
  • the pump is then connected either to a fuel supply line or via the other connection of the directional control valve to ambient air.
  • a fuel evaporator according to the invention has a housing with an inlet and an outlet and a radiator arranged in the housing.
  • the housing is a multi-part housing, wherein a housing main part surrounds the rod-shaped radiator and is joined to a housing end piece which has the outlet.
  • a multi-part housing structure has the advantage that the outlet for a distribution of the fuel in the exhaust line advantageous shape, such as a nozzle or diffuser shape, given and on the other hand, the production can be simplified because the introduction of the radiator in a housing main body and a subsequent assembly of the housing parts is very easily possible, for example by the housing main part is plugged together with the housing end, in particular the housing end is inserted into the housing main body.
  • the nesting can be carried out easily in the production and leads advantageously to overlapping surfaces of the two housing parts, which can be used for a cohesive connection, for example by welding or by soldering.
  • radiator protrudes into the housing end piece.
  • the radiator ends in the housing main body results in a better thermal coupling of the fuel and thus also a better evaporation when the radiator protrudes into the housing end.
  • the radiator is surrounded by a sieve, for example a metal mesh. In this way, the heat coupling of the fuel to the radiator can be improved.
  • the radiator is surrounded in the housing by at least one sleeve having a flow path with two sections arranged downstream of one another in the flow direction, wherein one of the two sections leads along the inside of the sleeve and the other section leads along the outside of the sleeve.
  • This can be achieved, for example, in that the sleeve is fastened at one end to the housing or the heating element, while the other end of the sleeve can be flowed around. In this way, an extended flow path and thus an enlarged evaporator section can be generated.
  • the tubular heater is surrounded in the housing of two or more sleeves, wherein one of the sleeves is attached at one end to the housing and another sleeve with the opposite end to the radiator.
  • the two sleeves can interlock and form a portion of the flow path between them. In this way, a meandering flow path and thus an advantageously large evaporator section can be specified.
  • a long evaporator section also has the advantage that the vapor pressure of vaporized fuel can be used to expel any existing unvaporized fuel residue.
  • Figure 1 shows the structure of a system for introducing fuel into the exhaust line of a motor vehicle in a schematic sketch
  • FIG. 2 shows an embodiment of a fuel evaporator in a longitudinal section
  • FIG. 3 shows a further embodiment of a fuel evaporator
  • Figure 4 shows another embodiment of a fuel evaporator
  • Figure 5 shows the housing end of the embodiment shown in Figure 2;
  • FIG. 6 is a sectional view of FIG. 5;
  • FIG. 7 shows the housing end piece of the embodiment shown in FIG. 4;
  • FIG. 8 is a sectional view of FIG. 7;
  • FIG. 9 shows a further embodiment of a housing end piece
  • FIG. 10 is a sectional view of FIG. 9.
  • FIG. 1 shows, in a schematic sketch, the structure of a system for introducing fuel into the exhaust gas system of a motor vehicle.
  • the illustrated system consists essentially of a fuel vaporizer 1, a metering pump 2, a 2/1-way valve 3 and a control unit 4.
  • the 2/1-way valve 3 forms a branch having a first branch with a fuel supply 6 and a second branch having an air supply 7, so that the inlet of the pump 2 and thus the fuel steamer 1 optionally fuel or air can be supplied.
  • the pump 2 In a first position of the 2/1 -Wegeventils 3, the pump 2 is connected to the fuel supply 6, so that the fuel evaporator 1 when operating the pump 2 fuel is supplied.
  • the fuel is vaporized in the fuel evaporator 1 and discharged through an outlet 10 as vapor 8 into the gas train.
  • the metering pump 2 In a second position of the 2/1 -way valve, the metering pump 2 is connected to an air supply 7, so that instead of fuel, air can be introduced into the fuel evaporator 1. In this way, fuel residues can be expelled in the fuel evaporator and at the same time burned coal, so that coking or sooting of the fuel evaporator can be counteracted.
  • FIG. 2 shows an embodiment of a fuel evaporator 1 in a longitudinal section.
  • the fuel evaporator 1 has a multi-part housing 11 a, 11 b having a housing main part 11 a, which surrounds a rod-shaped heating body 12, and a housing end piece 11 b, which has an outlet 10 for evaporated fuel.
  • the housing main part 11a is connected to a housing side part 11c having an inlet for fuel to be evaporated.
  • the housing parts 11a, 11b, 11c are preferably plugged together and welded together. In particular, the housing side part 11c may, however, also be screwed into the main part 11b.
  • the housing end piece 11b has a smaller outer diameter than the housing main body 11a in the illustrated embodiment.
  • the outer diameter of the housing end piece 11b decreases in this case to the outlet 10 in a stepped manner, namely in two stages.
  • the outlet 10 itself has a widening outwardly opening cross section and is formed in this way as a diffuser.
  • the opening cross-section may, for example, widen conically.
  • the radiator 12 is surrounded in the housing 11a, 11b by two intermeshing sleeves 13, 14, which form a meandering flow path between them.
  • One of the two sleeves 13, in the illustrated embodiment, the inner sleeve is connected to the housing 11 a.
  • the other sleeve 14 is connected at its opposite end to the radiator 12. In this way, advantageously results in an extended flow path for the fuel to be evaporated.
  • FIG. 3 shows another embodiment of a fuel evaporator 1, which differs from the embodiment described above by the formation of the housing end piece 11b.
  • the housing end piece 11 b is cylindrically shaped, thus has a substantially constant outer diameter.
  • the radiator 12 is surrounded by a sieve 15, for example made of a metal mesh. This sieve 15 projects together with the radiator 12 into the housing end piece 11 b and causes an improved heat coupling of the fuel to be evaporated to the radiator 12.
  • FIG. 1 Another embodiment of a fuel evaporator 1 is shown in FIG. This embodiment differs from the embodiment shown in Figure 2 only in the differently shaped housing end piece 11b.
  • housing end pieces 11b are shown in Figs.
  • the exemplary embodiment shown in FIGS. 5 and 6 has an expanding outlet opening 10, which is designed as a diffuser and in this way effects a particularly fine distribution of escaping fuel vapor or mist.
  • the outlet 10 of the housing end piece 11b is formed by a plurality of holes arranged next to one another. These holes 10 form a perforated ring and thus also cause a fine distribution of escaping fuel.
  • FIGS. 9 and 10 show a housing end piece of particularly simple design, in which the outlet 10 is formed by the end of a cylindrical extension.
